[background technique]
The source of damage of known bearing mostly is the material that outside foreign material enter the bearing interface or make bearing greatly and can not satisfies due to the continuous operation needs, development along with material engineering, the material of making bearing is also in progress at full speed, but how to prevent from or reduce foreign material as much as possible to enter another R﹠D direction that the bearing interface becomes industry, because bearing is relatively independent and an essential device, so under a lot of complex working conditions, move, must be directly and dust, the metal spittle, mud, water, greasy dirt, the acidic materials contact, the Environmental Conditions very severe, so structural design is vital, having good sealing property is the key technology that effectively prolongs the bearing pot life.
[summary of the invention]
In order to overcome the deficiency in the background technique, the utility model discloses the bearing structure of a kind of both sides double-sealing, the bearing structure of both sides described in the utility model double-sealing is by being provided with seal ring at bearing outer ring, and seal ring and inner ring two side cunning are joined, make Internal and external cycle form seal structure, prevent that foreign material from entering, overcome short drawback of bearing pot life effectively.
For achieving the above object, the utility model adopts following technological scheme:
The bearing structure of a kind of both sides double-sealing, described bearing comprises outer ring, inner ring, roller, retainer and seal ring, described outer ring outer rim is slick and sly shape, be symmetrical arranged scrobicular ring seal groove respectively around inwall in the both sides of outer ring inner face, between next-door neighbour's two scrobicular ring seal grooves, be respectively equipped with diameter inclined-plane from large to small, be provided with a ring plain between two inclined-planes; Described inner ring is two and is symmetrical arranged, the back of the width of two inner rings stack just is identical with the width of outer ring, wherein arbitrary interior coil structures from outside to inside is provided with a ring-type side seal groove for sidewall externally, described ring-type side seal groove to inner ring inwall is provided with ring-type transition side plane, to the inner ring inclined-plane that is provided with inclined-plane, corresponding outer ring between the buckling groove of middle part, described two inner rings form one by the snap ring clamping at the inner ring inwall; Be respectively equipped with roller between two inclined-planes, described outer ring and inner ring two inclined-planes and roller is installed on the retainer; Foreign aid's protruding ring of described two seal rings closely cooperates with the scrobicular ring seal groove of outer ring respectively, and the sealing bulge loop of described two seal rings is joined the bearing structure that forms complete both sides double-sealing with the side seal groove cunning of inner ring respectively.
The bearing structure of described both sides double-sealing, symmetrically arranged respectively scrobicular ring seal groove is two in the both sides of outer ring inner face.
The bearing structure of described both sides double-sealing, the foreign aid's protruding ring that is provided with the seal ring foreign aid is two.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
The bearing structure of both sides described in the utility model double-sealing, by foreign aid's protruding ring at the fixed seal ring of two scrobicular ring seal grooves of bearing outer ring, utilize the sealing bulge loop and the inner ring two side cunning of seal ring to join, make dust, the metal spittle, mud, water, greasy dirt, acidic materials under the complicated industrial and mineral be difficult to enter between outer ring, the inner ring, overcome short drawback of bearing pot life effectively.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, outer ring; 2, retainer; 3, roller; 4, seal ring; 5, sealing bulge loop; 6, side seal groove; 7, inner ring; 8, snap ring; 9, foreign aid's protruding ring; 10, scrobicular ring seal groove.
[embodiment]
Can explain the utility model in more detail by the following examples, the utility model is not limited to the following examples, and open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope;
The bearing structure of the both sides double-sealing described in 1 in conjunction with the accompanying drawings, described bearing comprises outer ring 1, inner ring 7, roller 3, retainer 2 and seal ring 4, described outer ring 1 outer rim is slick and sly shape, the both sides of 1 inner face are symmetrical arranged the scrobicular ring seal groove 10 around inwall respectively in the outer ring, the symmetrically arranged respectively scrobicular ring seal groove 10 in the both sides of 1 inner face is two in the outer ring, between next-door neighbour's two scrobicular ring seal grooves 10, be respectively equipped with diameter inclined-plane from large to small, be provided with a ring plain between two inclined-planes; Described inner ring 7 is two and is symmetrical arranged, the back of the width of two inner rings stack just is identical with the width of outer ring 1, wherein arbitrary inner ring 7 structures from outside to inside are provided with a ring-type side seal groove 6 for sidewall externally, described ring-type side seal groove 6 to inner ring inwall is provided with ring-type transition side plane, to inner ring 7 inclined-planes that are provided with 1 inclined-plane, corresponding outer ring between the buckling groove of middle part, described two inner rings 7 form one by snap ring 8 clampings at the inner ring inwall; Be respectively equipped with roller 3 between 1 liang of inclined-plane, described outer ring and 7 liang of inclined-planes of inner ring and roller 3 is installed on the retainer 2; Foreign aid's protruding ring 9 of described two seal rings 4 closely cooperates with the scrobicular ring seal groove 10 of outer ring 1 respectively, the foreign aid's protruding ring 9 that is provided with seal ring 4 foreign aids is two, and the sealing bulge loop 5 of described two seal rings 4 is slided with the side seal groove 6 of inner ring 7 respectively and joined the bearing structures that form complete both sides double-sealing.
Implement the bearing structure of both sides described in the utility model double-sealing, when being pressed in the bearing outer ring 1, foreign aid's protruding ring 9 of seal ring 4 (need to prove the combination of seal ring 4) for rubber and steel, the sealing bulge loop 5 of seal ring 4 and of sealing bulge loop 5 contact seals of the side seal groove 6 of the both sides outer rim of inner ring 7 with rubber seal 4, make sealed hollow of the inner formation of described bearing, described cavity can bear certain pressure.When bearing in when work, frictional heating between rolling that forms by roller 3 and the interior inclined-plane raceway, the bearing cavity temperature will inevitably raise, atmospheric pressure increases in the chamber of seal ring 4, form malleation, cause lubricant oil to leak easily,, can bear bigger pressure so rubber seal of the present utility model 4 closely contacts to after the interference fit with side seal groove 6; Effectively stop lubricant oil leak (and bearing rotates to getting rid of) outward.When bearing quits work, temperature also drops to ambient temperature gradually in the bearing, the bearing cavity hot air reduces, internal pressure can be lower than barometric pressure, the outside air band the trend that moisture and dust just can occur infiltrating, be subjected to the external pressure effect this moment, the sealing bulge loop 5 of rubber seal moves to the side seal groove 6 of inner ring 7, the effect of being under pressure of sealing bulge loop 5 makes the foreign aid's protruding ring 9 and 10 surperficial paste tightr of the scrobicular ring seal groove in the bearing outer ring 1 of seal ring 4 outer rims, stop dust, the metal spittle, mud, water, greasy dirt, acidic materials enter, and the small amount of moisture of accumulation in the chamber, through running next time, the small amount of moisture that accumulates in the chamber is cleared up away automatically by centrifugal action.
The utility model does not describe part in detail and is prior art.
